[Objective]To explore the characteristics of IR fingerprint and the changes of chemical components in Arecae semen before and after processing. [Methods]Arecae semen and Arecae semen tostum were detected by infrared spectroscopy and their characteristic peaks were assigned. [Results]IR fingerprint,characteristic absorption peaks and diagnostic characteristic peaks of Arecae semen and Arecae semen tostum were obtained. And we also discovered the change rule of IR fingerprint and chemical components before and after processing. [Conclusions]The method was simple,quick and sensitive,so it could be used in qualitative detection of Arecae semen and Arecae semen tostum and comparative analysis of their composition. And it also provided basis for the quality control.
